Abstract

The invention relates to a prefabricated thin concrete slab formwork structure. The prefabricated thin concrete slab formwork structure comprises prefabricated thin concrete slabs, a cushion layer, grooves, integrally-embedded connecting screws, angle iron, leveling base grout layers and cast-in-situ bored piles. The prefabricated thin concrete slabs adopt rabbets for connection, are provided withscrew holes and connected through the evenly-distributed angle iron. The connecting angle iron on the inner side is of an embedded type. The angle iron is provided with lead screw through holes connected with the integrally-embedded connecting screws. Grid cloth anti-crack tapes are arranged in seams between the prefabricated thin concrete slabs. Connecting studs are evenly welded to the angle iron on the inner sides of the prefabricated thin concrete slabs. Lugs are evenly arranged at the tops of the prefabricated thin concrete slabs. The prefabricated thin concrete slab formwork structure has the beneficial effects that an inner formwork of a sliding formwork system is evenly divided into cavities at equal intervals, adjustable sand partition plates are arranged in the cavities to forma limiting balance weight frame, and bags between the partition plates are filled with sand to achieve regional ballasting; and a plate vibrator and a vibrating leveling beam are arranged on a lower panel of a sliding formwork, so that the slope concrete pouring quality is further improved.

Description

technical field [0001] The invention relates to a prefabricated and assembled concrete thin-slab tire formwork structure and a construction method, which are suitable for rafts, foundation beams, caps, sump pits and other parts where side forms are not easily removed in construction engineering. Background technique [0002] At present, in the construction industry, during the construction of traditional building foundations, the side forms such as foundation ground beams, independent caps, and sumps are not easy to remove. Generally, the soil is excavated separately, and brick tire molds, that is, masonry brick tire molds, are often used as Formwork; brick membrane requires construction workers to build bricks in the foundation pit, so a larger construction space is required, which requires a larger area to be excavated when excavating the foundation pit. After the brick membrane construction is completed, the brick tire A large space is formed between the membrane and the ...
